"Table 3" of "Search for $\gamma$H production and constraints on the Yukawa couplings of light quarks to the Higgs boson"

Observed and expected constraints on the $\kappa_{u}$, $\kappa_{d}$, $\kappa_{s}$, and $\kappa_{c}$ couplings are shown using the $H \to 4\ell$ channel. In one scenario, all couplings except the one being shown are fixed at their SM values. In the other scenario, the Yukawa couplings for the three other light quarks are left unconstrained, and BSM contributions are allowed. The 68% (central value with error bars) and 95% (bracketed range or upper limit) CL exclusion regions are displayed.
